About This Video Content,
In this video Er. Narendra Patle ( 10+ Years of Experience in Execution, Billing, Planning & Monitoring work for high rise building projects) explained about Bent up bar ( Crank Bar ) concept in detail
what is "0.42 x d"
Cutting Length of Crank Bar

Important Usage of Bar Bending Schedule
Bar Bending Schedule (BBS) helps to determine the quantity of steel required in construction of your house. This helps to get the accurate estimation of steel
Once the calculation of cutting and bending is done it reduces the wastage of steel and it becomes economic
Once you get the reinforcement drawings, cutting and bending can be done at warehouse before transportation. It increases the speed of construction and the transportation cost also reduces.
Before placing the concrete if the bending and cutting length of TMT Steel bars are measured it becomes easier for site engineers.

What is a crank bar?
What Is Crank Bar & Why Crank Bars Are Provided In Slab?
A crank bar is provided to make RCC slab safe from compressive stresses. When these bars are provided, the strength and deformation capacity of slabs with bent up bars compared to slabs without bent up bars is sufficiently increased
Purpose Of Crank Bar
1. To resist negative bending moment (hogging).
2. To resist shear force which is greater at supports.
3. To reduce the risk of a brittle failure of slab-column connection.
4. To reduce the amount of steel used.
